SOLOMON DENEMARK, OF NEW YORK, N. Y.

SNOW-MELTING APPARATUS.

T 0 all whom it may concern:

Be it known that I, SOLOMON DENEMARK, a citizen o'l Russ1a, residing at New York city, hlanhattan, county and State of New quickly cleared after a snow -fall without carting.

In the accol'npanying drawings: Figure 1 is a side elevation of my improved snow melting apparatus; Fig. 2 a rear view thereof; Fig. 3 a vertical longitudinal section; Fig. 4 a cross section on line 44, Fig. 3, and Fig. 5 a plan of the snow melting receptacle.

The shell or casing 10 of a lire chamber 11 is mounted on wheels or runners 12. Within shell 10 is suspended a snow melting receptacle 13 having a longitudinally inclined and transversely curved bottom 14, -from the lower end of which there passes rearwardly an outlet tube 15 for the discharge of the water. A foot board 16, extending along each side of the shell 10, permits the attendants to shovel the snow into the open top of the receptacle 13. Fire chamber 11 surrounds receptacle 13 at both sides and also at the front, so that the heat of the ire chamber will be effectively transmitted.

Within the "lire chamber is contained a grate 17 that receives the fuel through a laterally placed oven door 18. The ash pan 19 is accessible through a rear door 20.

Upon a cross-piece 21, connecting runners 12 in front of shell 10, is-mounted a steam boiler 22 into the stack 23 of which opens fire chamber 11 through by-pass 24. The steam pipe 25 of the boiler, controlled by valve 26, connects with a steam coil 27 that lines receptacle 13 at its sides and bottom and thus forms a heated snow receiving bas ket within the receptacle. The bottom coils of this basket are elevated from bottom 14 "for a distance suflicient to permit the free discharge of the water through outlet 15.

Coil 27, after lining receptacle 13, as described, is provided with an upwardly extending leg 28 and a downwardly extending Specification of Letters Patent.

leg 29, the legs being joined at the top by a horizontal loop with a valve 31 which is thus readily accessible and permits the discharge of steam from the coil to be regulated. The lower end 01' leg 29 is extended rearwardly to a suitable distance within receptacle 13, as at 32, so as to subject the snow to the action of the ex haust steam. A trap 33 at the lowest point of the steam pipe and controlled by hand. rod 34 permits the water of condensation tobe discharged from the coil.

It will be seen that by the construction described. the snow in receptacle 13 is eflectively attacked. by heat generated without and also within the receptacle, so that it will be readily melted. The discharge pipe 15 may be provided with an elbow 35 and branch 36, for directing the water towards the gutters.

I claim:

1. A device of the character described, comprising a receptacle, an inclosed pipe extending along the sides and bottom thereof to form an inner snow receiving basket, a boiler connected to said basket, and a fire chamber surrounding the receptacle, substantially as specified.

2. A device of the character described, comprising a snow receptacle, a surrounding fire chamber, a grate within said chamberga 30. This loop is provided steam boiler, a coil of steam pipe within the receptacle that communicates with the boiler, a stack on the boiler, and a by-pass that connects the iire chamber with said stack, substantially as specified.

3. A device of the character described, comprising a snow receptacle, a steam boiler, a communicating steam coil which forms a snow receiving basket within the receptacle and is provided with an upwardly extending leg, a horizontal loop, a downwardly extending leg, and a valve within the loop, substantially as specified.

Signed by me at New York city, (Manhattan,) N. Y., this 16th day 01 May, 1908.

SOLOMON DENEMARK.
